Which statements are correct about becquerel (bq) and gray (gy) units? check all that apply. gray units measure the number of disintegration’s of radioactive atoms over a period of time gray units measure the radiation dose absorbed by any material becquerel units measure the radiation dose absorbed by biological tissue becquerel units measure emitted radiation gray units measure radiation dose gray units measure biological risk

The correct answers areGray units measure the radiation dose absorbed by any material.Becquerel units measure emitted radiation.Gray units measure radiation dose.
I hope this helps.

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j
